Cargo Features

strava-data has no features set by default.

strava-data = { version = "0.7.0-alpha.1", features = ["wasm"] }
wasm = wasm-bindgen

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.

wasm-bindgen wasm?
